Police are searching the mountains near a California ski resort for a fired Los Angeles officer suspected in three murders and who is threatening to kill all officers.

Police found Christopher Dorner's burned-out car in the woods near the town of Big Bear after a day-long manhunt.

Dorner wrote in a very long and often rambling on-line manifesto that he will wage "unconventional and symmetrical warfare" on the Los Angeles Police Department. He says the attacks will stop only when the department states what he calls the truth about his firing.

Dorner has already allegedly killed three people. They include one officer, the daughter of the retired police captain who represented him at his disciplinary hearing, and her fiance.

Authorities also say Dorner tied up the owner of a yacht in San Diego and tried to escape on his boat, but fled when the engine would not start.

Police have stationed guards at the homes of officers who are potential targets. Two women were wounded when police fired at them near one home, mistaking their truck for Dorner's.

The 33-year-old Dorner was a Los Angeles police officer from 2005 until he was fired in 2008 for what the department says was making false statements. He had accused a fellow-officer of kicking a suspect in the face and chest. He says that officer is still on the force while he was fired.

Dorner, an African-American, also accuses Los Angeles officers of racism and making fun of the Holocaust.
